CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS MEANS AND METHOD OF PROVIDING MOUNTED LITI-IOGRAPHS WITH NOTCHES FOR GENTERING Application filed June 9, 1930.

This invention relates to improvements in a means and method of automatically pasting lithograph-ed sheets upon cardboard mountings and simultaneously therewith producing guide notches in the sheet and mounting which may subsequently be used in properly aligning the design or the like formed upon said lithographed sheet with a die which may be adapted to out along the outlines of said design.

The utility, objects and advantages of the present invention will be apparent from the of the notching device.

Fig. 5 is a fragmentary top plan view of a portion of the composite board which has previously been notched.

Fig. 6 is a sectional view taken on line 66 of Fig. 5.

Referring more in detail to the drawings, 1 indicates a frame structure which is adapted to support rotatable shafts 2 and 2, which may be mounted one above the other. A roll 3 may be mounted upon shaft 2, and in a similar manner roll 3 may be mounted upon shaft 2. Each of the rolls 3 and 3 may be provided, respectively, with longitudinal slots 4 and 4 which open to the peripheral surface of each of the rolls. Shafts 5 and 5 may be longitudinally disposed within each of the slots 4: and 4:, respectively, and are adapted to carry a plurality of fingers 6 and 6, respectively.

A platform 7 may be positioned horizontally in a plane common to the upper surface of roll 3, said platform terminating adjacent the surface of said roll in an extension 8. The platform 7 may, if desired, be constructed of wood or some such like material, whereas the Serial No. 459,973.

extension 8 is preferably made of metal or some like material which offers little or no frictional resistance to the sliding of paper. A strip 9 may be mounted upon the under surface of the extension 8 and may be disposed longitudinally parallel with respect to the axis of the roll 3. The outer edge of said strip 9 may be disposed substantially tangentially with respect to the periphery of roll 3, just sufficient clearance being provided between the edge of strip 9 and the surface of roll 3 as to permit free rotation of the said roll.

A rod 10 may be longitudinally disposed above roll 3 and may be mounted at its ends in any suitable manner (not shown). Said rod 10 is adapted to support a retaining member 11, which in turn is adapted to support a movable arm 12 upon the end of which may be mounted conventional guide 13. The platform 7, including extension 8 andstrip 9, is adapted to support a lithographed sheet 14, which may have formed thereon by lithographing or printing a picture or design 15.

Mounted upon platform 7 is a guide 16 of conventional construction, which guide may be adjustable transversely with respect to said platform.

In operation the lithographed sheet 14 may be positioned upon platform 7 .and maybe squared thereon by maintaining the lon tudinaledgeof said sheet in contact with t eside guide 16 and the transverse edge of the sheet in contact with end guide 13. Upon rotation of roll 3 as slot 4 passes under strip 9, suitable mechanism (notshown) actuates shaft 5 rocking same and thereby rotating fingers 6 into the position shown in dotted lines in Fig. 1. In this manner the endsof fingers 6 grip the end of the lithographed sheet 14 and carry the same around upon the surface of roll 3.

' In a similar manner a blank sheet 17 may 7 be fed adjacent the lower periphery of roll 3, and similarly the same may be carried around the surface of roll 3 by fingers 6. 1

Simultaneously with the above mentioned operation, that is, the carrying of the lithographed sheet 14 upon the surface of roll 3 and the carrying of the plain sheet-liupon the surface of roll 3, a cardboard mounting 18 may be fed horizontally by suitable mechanism (not shown) to a position between rolls 3 and 3. The mounting 18 previous to its insertions between said rolls may have its surfaces coated with an adhesive material, such as paste or glue. It can readily be seen that when the sheets 14 and 17, respectively, contact the coated surfaces of the mounting 18 they will adhere thereto and be carried forwardly in the form of a composite sheet 19.

The frame structure 1 may support a pair of blocks 20 which in turn are adapted to provide bearings for shafts 21 and 22 which may be mounted one above the other. Each of said shafts may be provided with slots or keyways 23. A roll 24 may be slidably, but non-rotatably, mounted upon shaft 22 and may carry a die 25. A roll 26 may be similarly mounted upon shaft 21 and may serve as a bed roll against which die 25 is adapted to cut. Each of the rolls 24 and 26, respectively, may be provided with collars 27, which in turn may be provided with annular slots 28. A screw threaded shaft 29 may be threadedly mounted in one of the members 20 and may carry at one of its ends an element 30 which may be provided with fingers 31 adapted to co-operate with slots 28 in each of the collars 27. The opposite end of the screw 29 may be provided with a hand wheel 32 which upon rotation thereof may carry the element 30 in a direction parallel to each of the shafts 21 and 22. Hence, it can be readily seen that by suitable manipulation of the hand wheel 32 rolls 24 and 26 may be disposed upon shafts 22 and 21, respectively, at any desired position.

Upon the passage of composite board 19 from between rolls 3 and 3 one longitudinal edge of said board may be carried between rolls 24 and 26 and the edge of said board may be notched at desired intervals along the length thereof by the die 25. After leaving the notching unit the notched board 19 may be carried forwardly to a conveyor 33 which may comprise a plurality of conveyor belts 34 operating over a plurality of pulleys 35 mounted upon shaft 36. Shaft 36 may be rotated by belt 37 which, if desired, may be driven by the lower roll 3 in any suitable manner. It is to be understood, of course, that the speed of the conveyor 33 must be timed and equal to the peripheral speed of the rolls 3 and 3, since one portion of the board 19 is subject to the motion of the periphery of rolls 3 and 3, whereas the opposite end of said board may be subject to the motion of the conveyor.

Heretofore, in the art of mounting lithographed sheets upon a coardboard support for purposes of producing display cut-outs, the lithographed sheet containing the printed or lithographed advertising matter, design or picture, was pasted upon a cardboard mounting in any suitable uniting machine. After pasting, the sheet and cardboard were inserted by hand into a cutting machine provided with a suitable die cutter which con formed to the design or picture to be cut.

In inserting the composite board in the cutting machine, as can readily be seen, extreme care had to be exercised in properly aligning the lithographed design or picture with the cutting die so that the die upon descending would cut the lithograph exactly on the outline of the design or picture.

It has heretofore been the practice in cutting composite board to indicate a plurality of points upon the cutting plate of the die cutting machine upon which the composite board rested while being cut, usually by means of pin point guides Where upon said plate known points of the die cutter would descend. The composite board was then placed upon the cutting plate with the guides indicating points on the lithographed sheet which would correspond to like points on the die cutter. The lithograph and cardboard mounting were then cut.

As can readily be seen, this operation was apparently a hand operation and was slow and extremely dangerous to the operator of the die cut-ting machine.

In carrying out my invention, inasmuch as the edge of the lithorgraphed sheet is always a constant distance from the outer edge of the picture or design 15 printed upon said sheet, a notch 38 which has been cut by a cutting die 25 properly aligned with the longitudinal fee-d guide 16 will always be at a constant position with respect to the outer edge of the picture or design 15 printed upon the lithographed sheet 14. Hence, in the subsequent operation of die cutting the composite board 19 along the outlines of the picture or design 15 suitable lugs (not shown) may be provided in connection with the die cutting machine (not shown) at such intervals upon the plate of said die cutting machine that when brought into registration with notches 38 will properly align the dies and the picture or design 15.

It is to be understood, of course, that lu :2 other modifications of my invention may g gest themselves to anyone skilled in the art, and hence I do not wish to be limited to the precise structure shown, since my invention broadly contemplates means and a continu one method of uniting and notching a composite board at predetermined points a fixed distance from the edge of one of the sheets comprising the composite board.

It is to be further understood that the notches may assume any desired form, for instance, semi-circular, triangular, rectangular or the like. If desired, the notch provided in the composite board, instead of opening to an edge of the board may be totally enclosed, as for instance, the board may be apersugmeans tured at desired points, the center of the apertures being disposed a predetermined dlst-ance from either the edge of one of the sheets or from the outline of the picture or design upon the lithographed sheet.

Hence, by the term notch as used in the specification and claims is meant either an aperture opening to an edge of the board, or totally enclosed aperture in the board.

I claim as my invention:

1. A method of notching a relatively stiif multiply fibrous structure at a predetermined distance from the edge of one of the plies comprising said multi-ply structure, which comprises simultaneously adhesively uniting a plurality of plies, maintaining an edge of one of said plies in a predetermined plane, and notching said multi-ply structure adjacent an edge thereof a predetermined distance inwardly from said reference plane.
